OIL :Et/ECLAITJJER AND PURIFIER.

Application filed February 4, 19%2. Serial No. 534,141.

oi Texas, have invented certain new. and

useful Improvements in Oil Reclaimers and Purifiers; and I do hereby declare the following to be a full, clear, and eXactdescription of the invention, such as will enableA others skilled in the art to which it apper-` tains to make and use the' same. c c

The invention has relation` to means whereby used lubricating oil may be reclaimed and the impurities eliminated therefrom so that the oil may be advantageously used for lubricating purposes, thereby producing a material saving and obviating the waste incident to discarding used lubricating oil charged with slush and other impurities.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawing illustrates an embodiment of the invention it is to be understood that in adapting the same to meet diierent conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

The accompanying drawing illustratesv a perspective view of an oil purifier embodying the invention, parts being broken away.

The purifier comprises a receptacle 1 which may be of any capacity and whose bottom is preferably made rounded. The receptacle, as shown, is mounted upon legs which are attached to the bottom 2, the legs 3 being of any height and construction. A drain cock Ltis connected centrally with the bottom 2 and provides means for drawing off impurities or for emptying the receptacle, as required. A sight gage 5 is provided at one side of the receptacle to indicate the level of the eilt-herein. A heating coil 6 is located within the receptacle 1 and may receive a heating medium from a suitable source. A steam pipe 7, leading from a suitable source of supply, is connected with the inlet of the heating coil 6 and is provided in its length with a valve 8. A discharge pipe 9 connects with the outlet of Vthe heating coil 6 and conveys the water of condensation or spent steam to a suitable point of discharge. The discharge pipe 9 is provided in its length with a valve 10.. A screen 11 rests upon the heating' coil 6 and serves to retard the up-flow ot the oil and toseparate particles of impurities therefrom.y A pipe 12 connects with the receptacle 1 a short distance above the level of thescreen 11 and constitutes an outlet for the discharge of the oil after the impurities have been eliminated therefrom.

A funnel 13 occupies the upper portion of the receptacle 1 and is supported upon theupper edge thereof. A relatively large pipe 14 extends from the bottom of the fun-k nel 13 to within a short distance of the bot- 70 tom 2 of the receptacle and has a comparatively small opening 15 in its lower endY for the discharge ot the oil in the operation of the purifier. A screen 16 is disposed within the lower portion of the Jfunnel 13 75 and serves to remove particles from the oil in the process of reclaiming the same. A cover 17 is fitted to the top of the funnel 13 to exclude dust and foreign matter. A plurality of valves 18 are provided at one side v50 of the receptacle 1 and are disposed at different elevations and are utilized to draw oli the oil from the receptacle when cleaning the latter.

In the operation of the purifier, the fun- 95 nel 13 is removed and a quantity oi used oil is supplied to the receptacle 1 until the level corresponds approximately with the heating coil 6. l The funnel 13is now replaced and a quantity of the used oil is poured into the funnel to nearly or quite lill the same. The cover 17 is now placed in position and heat is applied to the coil 6 whereby to warm the oil adjacent or in contact with the coil. The

heating of the oil renders theV same more iuid and facilitates the precipitation of im purities. The oil contained in the funnel 13 passestherefrom to the lower portion of the receptacle 1 and is slowly discharged therein from the relatively small opening 15 `at the lower end of the pipe 14. The level of the oil in the receptacle 1 gradually rises until it reaches the overflow or discharge pipe 12 through which it passes and is delivered intoa suitable vessel (not shown) in condition to be again used for lubricating purposes, since all impurities,

slush and the like have been eliminated.

It is observed that the heating coil 6 eX- tends from the pipe 14 clear to the outer 110 wall ot the receptacle 1 whereby to provide a. maximum extent of heating surface.

cny

n may be requ1red.

A rod EZOeXtends through the funnel 13, pipe l111 and cover 17 and :1s provided `at its upper end with an eye or linger piece 21. The lower end ofthe rod 2O extends through the opening in the lower endloffth'e :pipe

14 and is provided with a' `stop22 which pre-v vents displacement of the rodwhen moved upward. The rod functions as' an agitator to prevent choking of the pipe '14 or lthe v outlet opening 15 so that ay How'` of the oil is assured. l p

What is claimed is.:

An oil puriercomprising a receptacle, a

heating coil within and spafnifngsaid 'freceptacle, a. -removble funnel avi'ng lits `i'lareol partadapt-ed to rest on the upper edge of said receptacle, a pipe depending from thehfunnel and through the coil with the V`discharge .end .thereof below the coil, a lscreen withinthe funnel, an agitator rod passing ,through said funnel and having a stop at the lower end thereof below the pipe,

a coverfor thev funnel through which said' rod passes, a screen within the receptacleand supported' said coil, outlet means from I they receptacle `'above the second "mem tio'n'edfscreen,- whereby' 'as `th'ef-oil level rises the Loil will pass through'the'` secondwlmen- :tione'd screenlandl then to said outlet means.
